A review article published in a special issue of Nature Reviews Neurology dedicated to traumatic brain injury (TBI) came with a plea for more long-term studies and identification of genetic risk factors for permanent disability stemming from chronic traumatic encephalopathy (CTE) and Alzheimer’s disease.

"Athletes such as David Duerson and Junior Seau have brought to light the need for preventive measures and early diagnosis of CTE, but it remains highly controversial because hard data are not available that enable prediction of the prevalence, incidence, and individual risk for CTE," Sam Gandy, MD, PhD, of the Icahn School of Medicine at Mount Sinai in New York City, said in a release. "We need much more in the way of hard facts before we can advise the public of the proper level of concern."
